collaboration focused on Pachycephala.More info: Pachycephala is a
genus of birds native to Oceania and Southeast Asia. They are
commonly known as typical whistlers. Older guidebooks may refer to
them as thickheads, a literal translation of the generic name,
which is derived from the Ancient Greek terms pachys "thick" +
kephale "head."
